SpirALL® Magnetic Flux Leakage (SMFL)

spirall-magnetic-flux-leakage

Technology Type

smfl-icon

Detection Capabilities

Coating and Lamination Anomalies
  • Surface Breaking Laminations
Mill Anomalies
  • Lack of Fusion
Construction-Weld Anomalies
  • Arc Strike
  • Cold Weld
  • Hook Crack
  • Seam Variations
Interactive Pipeline Threats
  • Stress Corrosion Cracking (SCC)
  • Selective Seam Weld Corrosion (SSWC)
  • Mechanical Damage
Crack Anomalies
  • Axial Crack-like
  • Longitudinal Seam Weld Crack-like 
  • Spiral Seam Weld Crack-like
Environmentally Assisted Crack Anomalies
  • Fatigue Crack

Proven over thousands of kilometers of pipeline, SpirALL® magnetic flux leakage (SMFL) technology overcomes the limitations of axial high-resolution magnetic flux leakage (MFL) alone in characterizing axially oriented defects in the pipe wall and long seams.  With SpirALL® magnetic flux leakage (SMFL) technology, pipeline owners and operators have an efficient way to detect crack-like defects in the pipe wall and long seams — including selective seam weld corrosion, hook cracks, lack of fusion, and surface-breaking laminations.

SpirALL MFL is combined with other technologies on the Multiple Dataset (MDS) platform to provide comprehensive threat assessment in a single inspection run. 

Key Features

  • Compact magnetizer design to create a spiral or transverse magnetic field that provides 100% coverage of the pipe wall
  • Detects axial planar or crack-like defects not detected by axial MFL
  • Able to distinguish attributes of long seam type — electric resistance welded (ERW), electric fusion welded (EFW), double submerged arc welded (DSAW), lap welded

Sizes

  • 6-inch through 30-inch*

* not available in some diameters
